There is "screen", a utility that acts as a layer between your login and the actual shell(s) you open. It allows to detach from and reattach to a session and would nicely fit this requirement. I'll assume you are not producing any graphics output to screen, that would be difficult. > > (3) Can I open several instances of R in parallel?

Not sure to which extent this is possible on LINUX. 2 or 3 should be no problem - you'll only be limited by memory (and cores to stay efficient). open as many connections (or consoles in screen) as needed and start an R in each. > > I assume that this questions are very naïve.
